Extract

The inheritance of carbamate resistence in the Fc strain of Musca domestica L. was investigated by the method described by Nguy & Busvine (1960) and more than one gene, most probably two genes, were found to be responsiple for carbamate resistence. A further experiment showed organophosphate and carbamate inheritance to be linked. As it was already known that the genes for organophosphate resistence were on the third and fifth chromosome, the third and fifth chromosomal resistence factors were separated by use of marker genes. Both factors gave low to moderate levels of resistence to organophosphates and carbamates. The third chromosomal factor appeared to be associated with increased oxidative activity and the fifth chromosomal factor with a modified aliesterase mechanism. The effect of the two genes was cumulative.
